To all who/1t t 'nm/ l/ conce/"rt: f

Be it known that l, ILLIAM A. KLrNG- BERG, a citizen of the United States, residing .at Elmo, in the county of Dickinson and State of Kansas, have invented certain new and useful Improvements in Changeable- Speed Gearing for Automobiles, of which the following is a specification. l

This invention appertains to gearing, being particularly designed for mechanicallypropelled vehicles whereby different speeds may be obtained and the machine reversedv the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result Areference is to be had tothe following description and accompanying drawings,

l/Vhile the inventionmay be adapted to v different forms and conditions by changes in is the recipient of the power to which the the structure and minor details without departing from the spirit or essential features,

thereof, still. the preferred embodiment is shown in the accompanying drawings, in which l Figure 1 is a top plan view of a powertransmitting gearing embodying the invention. Fig. 2 is a detail view illustrating the reversing mechanism thrown into gear.

Corresponding and like parts are referred to in thel following description vand. indicated in both the views of the' drawings by the same reference characters.

The mechanism embodies a shaft 1, which axle of the mechanism or the drive-wheels thereof are connected. Theshaft 1 is mounted inbearings 3, which may be of any struc-. tural type and supported in any manner dependent upon the nature of the machine to which the invention is applied.. A lever9 is conveniently arranged upon the machine, so as to be readily accessible from the drivers seat or other point to enable said lever to b readily operated.

Two s rocket-wheels 13 and 14 are loosely mounte upon the shaft 1 and are of different diameters, so as to effect dierent speeds.

The sprocketwheel 14 is of lar er diameter than the sprockets/'heel 13 an vis providedy upon .o posite sides with half-clutches 15 and 16.

one Aside only with a halfutch,-17 .,f` A sleeve 18 is slidably mounted uponlthe shaft 1 between the s rocket-Wheels 13 andlt'and iskeyed to sai shaft, so as to rotate there# with. Half-clutches are. formed or k'otherwise provided at opposite `ends ofthe sleeve 18 forv cooperation with the half-clutches 15 and 17, so as to cause one or the other of the s rocket-wheels'13 and'14 toA rotate with the T e sprocket-wheel 1.3. is plrovided upon y s aft l. A lever 19 is arranged for'coperay tion with the sleeve 18 .to effect a movement thereof to'cause either one ofthe s lrocket-4l wheels 13 or 14 to become clutche .to the shaft 1 Aor to admit of -both sprocket-Wheels rotating without imparting movement 'to said shaft, in which case the sleeve 18 occupiesa'n'v intermediate position.

The numeral 2 0,designates a ower-driven'. 1

shaft, which may bev the-cran -shaft ofen en ab are loosely mourited are connected/hres and 14. The sprocket-Wheels 21 vand 22 mayqfv be connected in any manner, soastdrotate as a single part and are adapted to be config@ nected wth the shaft 20 by means of a suitable clutch 25, vthe latter providing colvem.y

ient means for'throwing the power-transmit-.f..f

ting mechanism into and out of reference to the source ,of power j '.11

gear With- A reversing mechanism is provided and 'cof .i

operates with the shaft 1 and admits 'otre-# versing the machine without neeessitatin a stoppage of the primary motive power.- he

reversing mechanism'consists of-aftrain of.

gearing, which embodies spur-'gears 26, 27,-,v

28, 29, and 30, and a clutch devicee'omprising clutch members 31 andy 32. Theis 1'11- gears 26 and 32 are loose upon the sha 1'.

The spur-gears 27 and 28 are fast to a shaft 33, the spur-gear 27 being in mesh with the spurvgear 26 and the spurgear 28 being'in mesh with the spur-gear 29 and the latter inv turn freely'thereon. A half-clutch34 is proaft 1 and are at the same time adapted to vided upon the side of thespurfgear 2 6 adjacent to the sprocket-geerbt andisf'adapted to vintermesh with thehalffclutch'lto'cause ,i "1 the sprocketgwheel ,anrd pur-gearQQto vided with the helf-clutch 32 for coperation with the half-clutch 31, so :is to impart rota- 'tion to the shaft 1 in en opposite direction to the rotation of the sprocket-wheel 14, whereby admitting of the machine being quickly reversed without necessitating throwing` of the motive power out of action or requiring the reversing thereof. The heli-clutch 31 is fast to the shalt 1. rhe lever E) is connected to the spur-gears 26 end 30 in e wary to admit of simultaneous movement thereof in each direction.

It will be understood 'from the foregoing that the machine may be Llriven forward et two speeds according as one or the other of the spur-gears 13 and 14 is thrown into clutched engagement with the shaft 1 or is adapted to be reversed by operation ol the lever 9 without necessitetiirel e stopping of the engine or a reversing of he primary inotive power. It will be further observed that the mechanism is exceedingly simple end that the parts are compact/ly lrrrztngcd and are et alhtiines under control rind are further effective end not liable to derangement.

Power niey be transmitted 'from shaft 1 to the pert to be driven by any suitable means,

es sprocket-chain $39 and s rocket-wheel el), the latter being fest to the s aft 1.

The invention may be adapted to tractionmechines, automobiles, or other mechanisms requiring to be driven at di'l'erent speeds or to be reversed.

Having thus described is claimed as new is#- In power-transmitting gearing of the cheractor specified, the combinar-tion of' a shaft, a gear element loose thereon, e clutch coperating with said gear element and the shaft t0. throw the parts into and out of clutched engagement, e reversing mechanism comprising e train of gearing having two of its elements loose upon seid shaft, u clutch Jfor throwing one of said loose gear elements into and out of clutched engagement with the rst-mentioned gear element, and clutch forthrowing the other loose gear element into and out of clutched engagement with the saidshaft.
